发明名称 Container die system
摘要 An apparatus and method is provided for simultaneously forming at least two interconnected deep-drawn containers in a single sheet of paper stock or the like. The apparatus includes a female die assembly formed to include a material-receiving cavity situated between spaced-apart first and second container-forming cavities. A blade assembly pushes a portion of the single sheet downwardly into the material-receiving cavity to provide a source of excess paperboard material from which the paper for adjacent containers can be drawn. A male die assembly moves to engage the female die assembly and draw at least the excess paperboard material deposited in the material-receiving cavity to form containers in the first and second container-forming cavities. A draw ring holds the sheet against the female die assembly during operation of the male die assembly. The apparatus and method are usable to simultaneously draw a pair of containers joined together by a hinged section so that one container can be folded about an axis over the other container to provide a clamshell container assembly.
